Frequently we hear examples of how some things are worse since Vatican II -- the "clown mass" seems to be the most obvious. While I don't disagree with the idea that some thing are indeed worse now, I want to point out that things weren't necessarily that great in the late 19th and early 20th centuries either.
1. Mistreatment of Eastern Catholics. (Some of you may be familiar with this famous line, and the story that surrounds it: "the presence of married priests of the Greek Rite in our midst is a constant menace to the chastity of our unmarried clergy, a source of scandal to the laity and therefore the sooner this point of discipline is abolished before these evils obtain large proportions, the better for religion, because the possible loss of a few souls of the Greek Rite bears no proportion to the blessings resulting from uniformity of discipline.")
2. The Catholic Encyclopedia. Many different examples could be furnished to explain why I included this in the list, but I'll just refer you to what it says about Photius of Constantinople:http://www.newadvent.org/cathen/12043b.htm
3. Pope Pius IX's statement "I am tradition." (Although I'm not certain if this is an established historical fact or a rumor.)
4. General hostility toward Protestants and Orthodox. (I don't think I need to explain that one.)
